Other_dict must be a display object (dictionary)

Question

I have the following context processor:

def btc_price(request): price = get_price() return {'btc_price', price} 

In case that matters, here is my get_price function:

 def get_price(): now = datetime.datetime.now() if PriceCache.objects.all().exists(): last_fetch = PriceCache.objects.latest('time_fetched') time_last_fetched = last_fetch.time_fetched day = datetime.timedelta(days=1) if now - time_last_fetched > day: api_url = urllib2.Request("https://www.bitstamp.net/api/ticker/") opener = urllib2.build_opener() f = opener.open(api_url) fetched_json = json.loads(f.read()) cost_of_btc = fetched_json['last'] PriceCache.objects.create(price=cost_of_btc, time_fetched=now) last_fetch.delete() return cost_of_btc else: return last_fetch.price else: api_url = urllib2.Request("https://www.bitstamp.net/api/ticker/") opener = urllib2.build_opener() f = opener.open(api_url) fetched_json = json.loads(f.read()) cost_of_btc = fetched_json['last'] PriceCache.objects.create(price=cost_of_btc, time_fetched=now) return cost_of_btc 

I declared a context processor in TEMPLATE_CONTEXT_PROCESSORS, which looks like this:

 TEMPLATE_CONTEXT_PROCESSORS = ( "django.contrib.auth.context_processors.auth", "django.core.context_processors.debug", "django.core.context_processors.i18n", "django.core.context_processors.media", "django.core.context_processors.request", "Computer_store.processors.btc_price", ) 

And the request context is correctly defined in my render_to_response function.

 return render_to_response('home.html', {}, context_instance = RequestContext(request)) 

However, when I try to run this code on the main page, I get a strange error. TypeError at / other_dict must be a mapping (dictionary-like) object.

Full trace is available here .

Similar to

 return {'btc_price', price} 

should become:

 return {'btc_price': price}
